The Midnight Recovery Concentrate is one of Kiehl's most popular product and they said that they have been selling 1 every minute globally! Since the limited edition bottle cost the same as it's original version (£36.00), it's definitely worth buying to support their campaign, especially when you are already using it like me. We have to restock sometime anyway. I'll have to pop down to my nearest stockist to get myself one though as it's unavailable online due to popular demand. The message on the website said that there should be stock at the stockists, so grab yours while there is any left!
